Could not find a version that satisfies the requirement MontagePy

[david-guyon]

Hello,

I'm trying to use the new python version of Montage (MontagePy, version 6.0). I'm working on a Debian 3.16, with both Python 2.7.9 and Python 3.4.2 and pip 18.1. When I execute pip install MontagePy, I get the following error:

Could not find a version that satisfies the requirement MontagePy (from versions: )
No matching distribution found for MontagePy

In the documentation it seems that nothing else than the pip install command is required. Is it true? Additional details on the installation process of MontagePy would be appreciated.

Kind regards.

FYI, the next Debian 10 "Buster" release will come with a proper python3-montagepy package.

I am having the very exact issue. I am also working with Python 2 and so have the similar error. Kindly please someone give a solution for Python 2 and not for Python 3. Thank you!

Keep in mind that Python 2 will die by the end of this year. This includes a large number of important science packages. https://python3statement.org/

I understand it. I am trying to use another package written for python2 and uses Montage. This is the reason why I am insisting on python2. For the rest of my research, I use Python 3.

I just encountered the same strange thing. pip install MontagePy used to work fine before.

This is under Python 3.8.5, pip 20.0.2

But only on my laptop, so please ignore, sorry.

Hello,

I am now having this same error message when trying to install MontagePy, either locally or in a mybinder notebook environment.

ERROR: Could not find a version that satisfies the requirement MontagePy (from versions: none) ERROR: No matching distribution found for MontagePy

pip version 23.1.2, Python version 3.8

Any advice here would be much appreciated.

Since MontagePy (a lot of) compiled code as shared-object libraries, an install package must be separately build for each platform and version of Python. For Python, we use Anaconda releases for simplicity. As of this date (June 9), Anaconda does not have a full release for Python 3.11, so the latest MontagePy available is for Python 3.10. If there is some serious need for a 3.11 version before the next Anaconda release (which tend to be one and occasionally two a year), we can take a look at doing that using the "raw" python release.

Using macOS 14.4 and python 3.10, it doesn't work either:

$ python3 -V                                                                                          14:38:13
Python 3.10.13
$ pip3 install MontagePy                                                                              14:38:15

Installing directly from wheel also fails:
